  • Figure 8 is a schematic diagram of a second embodiment of the invention.
  • a navigational aid puck or cursor device 200 is of the type described in our copending International patent application WO87/07013, although it differs from it in its detailed design and is for use in the navigational aid system disclosed in that patent application.
  • Figure 1 illustrates generally how the puck 200 is placed on a chart 100 which is clipped onto a digitising pad 101 by clips 102.
  • the puck 200 is electrically connected by a cord 103 to a computer (not illustrated) via a signal processing unit or digitiser 104 which is carried by the digitising pad 101.
  • the digitising pad 101 would preferably be of the construction disclosed in our copending UK Patent Application No 8828864.2.
  • the puck 200 has a body portion 201 at one end of which is formed a positioning portion 202 which includes an aperture 203 through which the navigational chart may be viewed when the puck 200 is placed flat on the chart.
  • the aperture 203 is filled by a window element 204 which carries a centre mark 205.
  • the body portion 201 acts as a handle and incorporates a digital display 206 and a number of key buttons 207 by which data can be entered in the manner disclosed in our copending International application WO87/07013.
  • the puck 200 is electrically connected by the cable 103 to a computer in the manner disclosed in our copending International Patent Application No WO87/07013.
  • each light shines through an arrow shaped pointer window, the purpose of these lights being to indicate to the user in which direction to slide the puck over the surface of the chart 100, in the manner described in our application WO87/07013.

  • a dot matrix display 120 is employed for displaying sixteen characters in an eight column by two row arrangement (A-P) . Each character can be formed by a nine by seven array of dots.
  • the driver 112 has a sixteen byte character code memory using a four bit address line 116 and a seven bit data line 118.
  • the data is supplied in the form of the ASCII code of the respective character to be displayed.
  • the device also includes a character generator 140, which contains, for each, ASCII code, a bit map of the respective character.
  • the driver 112 also includes a display memory 142 having one bit for each dot of the display 120 so that the display memory can contain a bit map of the desired display.
  • the driver is operable to look up the bit map for each character code stored in the character code memory 112 and to copy that bit map into the respective portion of the display memory.
  • the display 120 then produces a display corresponding to the complete bit map in the display memory.
  • two modes of operation can be selected. This is done by a signal to a mode input 134.
  • the mode signal is "0" the device operates as described above; however, when the signal is "1", the following changes are made.
  • a different bank 140B of the character generator 140 is used instead of the bank 14OA used in the other mode.
  • This bank 140B contains for each character a bit map which is upside down compared to the corresponding bit map in the bank 14OA.
  • the sixteen character codes in the memory 114 are used in one order to produce the display portions A to P in the display 120 when the mode signal is "0", when it is "1” the sixteen character codes are used in the opposite order to produce the display portions A to P.
